Question: Three 100 MVA, 76.2 kV/45 kV single phase transformers are connected in Y-Y to form a three-phase transformer bank. If leakage reactance of primary coil

Three 100 MVA, 76.2 kV/45 kV single phase transformers are connected in Y-Y to form a three-phase transformer bank. If leakage reactance of primary coil is Xl1=5.81 , and leakage reactance of secondary coil is Xl2=1.01 , (a) find the per-unit model of the transformer. (b) Find the per-unit model of the transformer if the three-phase transformer was connected Y-
